Quick Answer: The Bissell Big Green Machine Professional (86T3) is a $429.99 pro-grade upright carpet cleaner built on the same commercial platform behind Bissell’s rental kiosks, with an 8-Row XL DirtLifter PowerBrush, dual 1.75-gallon tanks, and a 10.5-inch cleaning path. At 42 lbs it’s by far the heaviest machine this site covers, but it also carries the highest customer rating — 4.8 out of 5 stars across 2,086 reviews on Bissell.com — and a 5-year limited warranty. It’s the pick for large homes and heavy, recurring deep cleans, not for apartments or occasional spot jobs.
Bissell built its rental business on this platform, then started selling it outright. Here’s what the 86T3 actually delivers for $429.99, and who should spend the extra money over a standard upright.
Big Green, by the numbers
- $429.99 — the current price on Bissell.com (verified 2026-08-09), and a real correction: this site had cited an approximate ”~$400” for the Big Green in earlier roundups, which had drifted stale.
- 4.8 out of 5 stars across 2,086 reviews — per Bissell.com, the highest customer rating of any machine reviewed on this site, ahead of the ProHeat 2X Revolution and the CrossWave Pet Pro.
- 42 lbs — nearly three times the Little Green Max Pet’s 8.2 lbs and well above the ProHeat 2X Revolution Pet Pro Plus’s 17.5 lbs, per Bissell’s own spec sheets.
- 5-year limited warranty — matching the ProHeat 2X Revolution’s coverage and two years longer than the CrossWave Pet Pro’s 3-year term.
What’s good
| Strength | Why it matters |
|---|---|
| 8-Row XL DirtLifter PowerBrush | Wider, denser brush contact than any residential upright on this site — built for ground-in soil, not surface dirt |
| 10.5" cleaning path + 1.75-gal dual tanks | Covers more floor per pass and per tank fill than a standard upright, cutting refill trips on large rooms |
| 4.8/5 across 2,086 reviews | Highest customer rating of any machine this site has reviewed, per Bissell.com |
| 3x 8-oz PRO MAX formula included | More trial solution in the box than the budget TurboClean Pet's two bottles |
What’s not
- 42 lbs is genuinely heavy. It’s not a machine you carry up stairs — plan to keep it on one level or accept the workout.
- No CleanShot pretreater. Unlike the ProHeat 2X Revolution, there’s no onboard sprayer for pretreating a stain before the main pass.
- No Express Clean fast-dry mode. The ProHeat’s roughly 30-minute dry-time feature isn’t here; expect standard dry times on a machine this size.
- $429.99 is a real commitment. It costs more than two ProHeat 2X Revolutions, and is overkill for anyone who only spot-cleans or lives in an apartment.

Who should buy it
Buy the Big Green if you deep-clean a large home regularly, manage a rental turnover, or want rental-kiosk-grade suction without the drive to the grocery store and back. Its 4.8/5 rating and 2,086 reviews — the highest of any machine this site covers — back up that it holds up to repeated heavy use, and the 5-year warranty matches Bissell’s most premium consumer coverage. It’s also the machine our best carpet cleaner for high-traffic areas guide recommends for the heaviest daily wear.
Skip it if you live in an apartment, only need spot and stain cleanup, or want a machine you can carry between floors — the ProHeat 2X Revolution Pet Pro Plus covers most households at less than half the weight and price, and the Little Green Max Pet handles spots and stairs at a fraction of both.
The bottom line
The Bissell Big Green delivers what its $429.99 price and 42-lb frame promise: the widest, most aggressive cleaning path and the highest customer rating of any machine this site has reviewed. It’s not the right choice for small spaces or occasional use, but for large homes and recurring deep cleans it’s rental-kiosk power without the rental trip.
